There is a bios issue for me on 5800X3D- B550 Gaming Plus - 7C56v1B.

The offset voltage applies a positive offset to the CPU instead of a negative one ( French MSI SAV said you don't use the right bios for this cpu... :confused:, so they probably won't forward the issue).
And i'm also quite sure there is an issue with the ERP ready which seems to be always ON (no power to USB when set to OFF). This was working fine when I was with my 3700X - Bios 7C56v17
This seems bad. I hope this problem will get addressed soon. Sounds like you cannot apply a negative offset to this CPU and thus you cannot undervolt this CPU. Undervolting is the most important feature if you want to bring temperatures down with very little performance loss. So hopefully the will be an update for your board.

Humm so did thay say what Bios it should be

Not sure what the exact bios setting are you get as do not have that CPU
But I think you can set a negative
Should be this one

You need to set a Wake event for the USB power to be enabled This Is what I have always done

They said I should rollback to 7C56v19 but doing so makes me loose the CPU Offset Voltage and the KomboStrike.
As for the cpu offset voltage on my motherboard, I have an entry "CPU Offset Voltage (-) AUTO" instead of "CPU Voltage AUTO" since its locked on this processor.

The minus should mean undervolt right ?

With default setting during a cinebench cpu voltage is 1.19V
If I set "CPU Offset Voltage (-) 0.05V" during a cinebench -> 1.24V .

For the USB power, I will give it a try. I probably had this one turned ON before and just couldn't remember.

So if you click on Auto for CPU offset are there any other options like AMD override Voltage Offset or can you type in a number like -0.050v

That offset is on top of the Curve Optmiser settings

I forgot about this setting as well

Well, you are in Global Forums and I will see if I pass it on to our Contact to take a look. As it does seem Odd for them to say that it is the wrong BIOS.

I also meant to ask do you have LLC setting in BIOS if so set it to humm 6 or 8 may have to play with that setting to get the best results if it is there will be under Digital All Power

I normally set mine to 3 or 4 for a more even voltage across all loads.

I only have the option "CPU voltage offset (-)" you see on the screen. If I had to guess I would say it's just an offset error in the BIOS (offset set in the .c code :-))

LLC was already set to 4 so no changes here.

Regarding the SAV " Pouvez vous aller sur notre site et faire un "downgrade " de la version du bios a la version 7C56v19 qui est plus adapté au modèle de votre processeur .Merci. "
Translates to "Can you go on our website and do a downgrade from your current bios version to the version 7C56v19 which is more suitable for your CPU".

Hi have heard back from Our contact and testing has been done

Our Contact has tested various offset values with the same setup CPU 5800X3D + Bios - 7C56v1B

1673322516576.png

It was found that when in BIOS, for some reason, default Vcore does not do a negative offset when the value is within 0.05v.

When in the OS, the offset does work as expected. Although the performance seems to drop a little, however, it does reduces heat generated from the CPU.

This issue is still under investigation
And Could you please go into bios and go to OC Profiles and save your Bios profile to USB and pm it to me This will be passed on to My contact for further investigation.

It was also noticed that while in the BIOS as the CPU temp increases V-Core also increases
This will likely need to be looked at as well but should not be a problem while in the OS


Once you have saved your OC profile can you please do a Clear Cmos just in case there is some other setting that may be causing the problem?
And try the Offset again.
But I would really like for you to save and then send me your BIOS Configuration befor you do a Clear Cmos

What is looking strange for me is Ryzen Master reporting a positive offset but for HWinfo it's not, weird

SO ya the temps do seem a bit on the high side what kind of cooler are you using?


I found that with the R9 5900X Air was not cutting it on a full core load so went to an AIO water cooler and it made over a 20c difference in cooling I was Using the BeQuiet TC Cooler which is rated to 230 TDP and it was struggling to keep it below the thermal limit of 95c I had set for it in BIOS.

So our Contact has been busy running tests with your Saved Bios Profile.

with just a couple of changes listed below

1. Offset settings

2. Set the fan to run at full speed to improve thermal dissipation.

3. Kombo strike set either disabled or mode 3

KS StatusOffset (V)RM Vcore (V)RM Power (W)HWinfo Vcore (V)HWinfo Power (W)CPU Temp (C)Cinebench
Disabled01.28690.7011.242119.7568613946
Disabled0.11.26368.1071.13689.67012493
301.20081.8081.168103.5337814345
30.11.24968.0561.1288.8797113628

It was noted that HWinfo data is closer to the real Vcore value.

Power consumption and temperature should be proportional to Vcore but not the other way.

Can you Check your power consumption and CPU temperature to see if it also does the same? More power more temp should increase.

Testing found that Kombo Strike enabled will give more optimized results compared to the default one.

Using KomboStrike and Vcore offset at the same time may cause instability MSI RD do not recommend you do that from their testing results.


Screenshots have been included and include Voltage readings taken at the same time with AMD Ryzen master and HwInfo64

I have noticed the same in my set-up that Ryzen master does not seem to be correct as I run a Curve optimiser of -30 and a -0.1000v Offset and Ryzen master does not show this but HwInfo64 dose

Hope all this information Help

PPT column is in Watt (clamped at 100W in bios) and not in °C.
Temp were in between 68°C 76°C with a NH-U12S.

So it seems that in fact there is no issue on this motherboard (appart from the undervolt not being applied below -0.05V) but rather an issue on Ryzen master tool.


Also when comparing my KomboStrike 3 0V offset against your contact I can pull 400 more point with a slightly lower Vcore. But I give the benefit of the doubt to the memory 3200MhzC16 vs 2134MhzC15 + Infinity Fabric running in 1:1.

Yep, it seems that way but at least you know it all working as expected now.

Now to try and get on top of the other problems users have reported.


If you have concerns again just pop back and ask.

And I still can not work out why they suggested this option.

Hi, so I got the 5800x3d on a deal pairing it with the MSI x570 Unify (latest bios 7C35vAE ) cooled using NZXT Z73 360mm AIO had no issues cooling the 5900x with it, looking around and comparing temps what others are getting doing cinebench r23 multi run , at stock it gets to 85c doesnt feel right when on 360 aio thats only 5c off throttling temps and its not even summer , I see others with different boards also with 360 aio's and say they get 63-70c ?

using Kombo strike level 3 it drops and caps out at 80c my cb23 scores seem to be fine 14400-15000
single core cb23 run it seems to cap at 51c

during gaming it seems to be inline what others are getting averages 55c-65c , just spiderman with RT max + DLSS quality pushes 75c but that game is known for that and see another getting the same with the 5800x3d on that game with gigabyte board and custom 280mm rad

I also flashed older bios 7C35vAC but no longer have Kombo strike option in bios, so used PBO2 tuner in windows and set to -30 doing cb23 multi run it gives 76c so its slightly improved and slightly better cb23 multi score

package power with -30
7C35vAE was around 113w-116w
7C35vAC 106w

I much prefer to use bios with kombo strike dont really like having to add extra stuff in windows, during gaming it seems fine but would like to know why I get higher temps when fully stressed

looking at the above results the temps seem to be matching up with cb23 runs so can at least rule out cooler issue or cpu, I even reapplied paste and re mounted cooler thinking it could be that

any idea whats going on ?

Those screens shot I posted are with a 360 maxed out on pump and Fan speed that CPU just runs hot

yeah but others getting better results , one Dark Rock Pro 4 gets 63c another with 420 aio & it doesn't go above 67°C during Cinebench R23

room temps at 19c , all 3 rad fans 900rpm , pump pretty high
one thing older 7C35vAC bios temps are better stays locked 4450 while cb23 multi run but doesnt have kombo strike

anyway in gaming it seems to be inline with others which is the important thing as I will only game and do general tasks , maybe will get improved bios later on

weird bug sleep bug once I come out of sleep performance improves

-30 all cores , msi x570 unify 360 aio Z73

Would not be concerned my Score with Cineabench quite often varies by 200 to 300 points
